Desktop connects intermittently

I'm having issues connecting to the internet on my desktop via a wireless network. I'm able to connect on my phone, laptop, and tablet without any issues. Additionally, my desktop seems to be connected in the network and sharing center, but most of the time, webpages won't load. When I run diagnostics on the wireless network connection,it says that my "broadband modem is experiencing connectivity issues." Power cycling the modem does nothing. In command prompt, entering ipconfig/release and then ipconfig/renew will sometimes help, but not always.

I'm running Windows 7 on a Gateway PC, and have a Netgear RangeMax wireless-N adapter. Thanks in advance for any advice!

 

Thanks for the reply. Gateway is model DX4870 . I'm running Windows 7 Home Premium service pack 1 (build 7601) and I'm up to date on all important updates. No yellow ! marks in device manager. I use AVG Antivirus Free; I don't think I have any additional firewalls or antivirus that runs constantly (just tools like MalwareBytes and SuperSpyWare). I should also mention that I'm using the Netgear dongle because my wireless card that came with it gave out.

Thanks again for your time!

 

Ok, I was sure it was a problem with my computer since other devices still work fine, but when I switched internet providers today, the problem was resolved.

 

old hp workstation upgrade sound card windows 7

Hi all.
am having intermitant audio play back issues with my bluetooth speaker,after a lot of experimentation,I found with my son's Iphone it works-no problem,so I have pinpointed it down to my old computer.
I have a HP workstation Xw6000,I upgraded to windows 7,from XP.
I have no yellow signs on my driver manager and I believe I have all the updates from windows for 7.
My son says they did not make sound driver for windows 7,only for XP,he has searched and not found any?
Could it be that I need a better sound card? an upgrade? :confused

 

Also when I change pages,the sound goes off foe a second?
